If you have ever walked up to an ATM to withdraw cash only to decide against it after noticing a telephone or ethernet cord snaking from behind the machine to a jack in the wall, your paranoia may not have been misplaced: ATM maker NCR is warning about skimming attacks that involve keypad overlays, hidden cameras and skimming devices plugged into the ATM network cables to intercept customer card data.
Most of the ATM skimmers I’ve profiled in this blog were parts designed to mimic and to fit on top of existing cash machine components, such as card acceptance slots or PIN pads. But sometimes, skimmer thieves find success in modifying or wholesale swapping out ATM parts with compromised look-alikes.
ATM skimmers come in all shapes and sizes, and most include several components — such as a tiny spy cam hidden in a brochure rack, or fraudulent PIN pad overlay. The problem from the thief’s perspective is that the more components included in the skimmer kit, the greater the chance that he will get busted attaching or removing the devices from ATMs.
